Smart Offers is a great app for my e-commerce store. I highly recommend it as a way to offer upsells, cross-sells and downsells in the checkout process. It is easy to setup and customize to get running in no time, but also has powerful functionality so that you can direct its behavior exactly as you desire. Customer support is top notch! They respond quickly and listen to product feedback from customers. Mansi, in particular, helped me out a great deal and really took the time to scrutinize my offer processes and helped me correct some errors I was making in the implementation of my offers. An overall great plugin and customer support to back it up.
